Testing Inverse Gaussian Versus Log Normal [PDF]

open access: yesThe Egyptian Statistical Journal, 1991
The inverse Gaussian distribution has been proposed as a model for distribution of life times. It is considered as an alternative to other observed distributions in particular to the lognormal.

Hutchinsonian Ratios and Log-Normal Distributions [PDF]

open access: yesEvolution, 1985
It has been proposed that competition among members of a species assemblage leads to constant size ratios among the species ranked in order of average individual size, or to large minimum size ratios (for references, see Simberloff and Boecklen, 1981).

Bayesian inference for Poisson and multinomial log-linear models [PDF]

open access: yes, 2009
Categorical data frequently arise in applications in the social sciences. In such applications,the class of log-linear models, based on either a Poisson or (product) multinomial response distribution, is a flexible model class for inference and ...

Analyses and Modeling Impulse Noise Generated by Household Appliances

open access: yesAdvances in Electrical and Electronic Engineering, 2014
This paper describes analysis of impulse noise generated by small household appliances. Furthermore we propose a new model of impulse noise based on the averaged power spectrum and the random phase generation with various phase distributions.

Non-stationary log-periodogram regression [PDF]

open access: yes, 1998
We study asymptotic properties of the log-periodogram semiparametric estimate of the memory parameter d for non-stationary (d>=1/2) time series with Gaussian increments, extending the results of Robinson (1995) for stationary and invertible Gaussian ...

Misspecification Tests for Log-Normal and Over-Dispersed Poisson Chain-Ladder Models

open access: yesRisks, 2018
Despite the widespread use of chain-ladder models, so far no theory was available to test for model specification. The popular over-dispersed Poisson model assumes that the over-dispersion is common across the data.
